That's funny, I just dropped by to post a similar picture.

I was trying to find something on the Rouge (.33 Cd) and found the Murano (.31 Cd) instead.

2015 Nissan Murano sets new airstream standards for the segment - Torque News
.

Changes like the removal of the D-pillars from sight, the "fast-back" hatch, smoother fenders, and small vortex-creators come together to give the 2015 Nissan Murano a Cd of just 0.31 - on par with some of the world's priciest and most acclaimed sports cars.

Good to hear that a low Cd is now a main stream marketing tool to indicate value/cost/price.

BMW M3 Coupe: Aerodynamics | BMW South Africa

Wind power.
The aerodynamics of the new BMW M3 Coupe.
The optimised aerodynamics in the BMW M3 Coupe ensures that downforce is both cooled and increased at the same time. The left opening near the powerdome channels additional air to the intake air plenum. The M rear apron with diffuser ensures controlled airflow along the car’s underbody. And the M front air dam with integrated air inlets cools the engine. The result? Added downforce for added thrills.

Aero Testing the 1973 Mopar Missile Drag Racing Car (Plymouth Duster)
Aero Testing the Mopar Missile

The Chrysler drag race group had a very limited budget. The renting of a full size wind tunnel, if it was available, was
out of the question. They had to do it the old fashion way, taping cotton tufts to the car, then using a chase car with
the racer traveling at high speed passing the chase car.

What the heck?

There are about a dozen photos of the front, and not one of the rear where drag is created.

Maybe they were just testing the hood scoop?

A little off topic, but sort of pertains to the subject.
